What is a Pronoun?

A pronoun can replace a noun or another pronoun. You use pronouns like "he," "which," "none," and "you" to make your sentences less cumbersome and less repetitive.

Grammarians classify pronouns into several types, including the personal pronoun, the demonstrative pronoun, the interrogative pronoun, the indefinite pronoun, the relative pronoun, the reflexive pronoun, and the intensive pronoun.
Personal Pronouns

A personal pronoun refers to a specific person or thing and changes its form to indicate person, number, gender, and case.
Subjective Personal Pronouns

A subjective personal pronoun indicates that the pronoun is acting as the subject of the sentence. The subjective personal pronouns are "I," "you," "she," "he," "it," "we," "you," "they."

In the following sentences, each of the highlighted words is a subjective personal pronoun and acts as the subject of the sentence:
